Photon Emission Rate Engineering using Graphene Nanodisc Cavities
Anshuman Kumar, Kin Hung Fung, M. T. Homer Reid +1
In this work, we present a systematic study of the plasmon modes in a system of vertically stacked pair of graphene discs. Quasistatic approximation is used to model the eigenmodes…
Super-resolution image transfer by a vortex-like metamaterial
Hui Yuan Dong, Jin Wang, Kin Hung Fung +1
We propose a vortex-like metamaterial device that is capable of transferring image along a spiral route without losing subwavelength information of the image. The super-resolution…
Ferroelectric-Gated Terahertz Plasmonics on Graphene
Dafei Jin, Anshuman Kumar, Kin Hung Fung +2
Inspired by recent advancement of low-power ferroelectic-gated memories and transistors, we propose a design of ferroelectic-gated nanoplasmonic devices based on graphene sheets cl…
